Huckabee talks with his running mate, Stephen Colbert

If anyone has missed the previous times that presidential hopeful Mike Huckabee has visited "The Colbert Report" and invited Colbert to be his running mate, Huckabee was on again last night. It was among the funniest things I've ever seen, and if it truly wasn't scripted, Huckabee is quite possibly as funny as Stephen.

You decide for yourself. Was it written, or off-the-cuff?

The one thing that makes it seems off-the-cuff is how often Huckabee ends up laughing at what Colbert says, and Colbert even fights laughter when Huckabee says he'll send him a memo and underline in red all the parts they need to believe.

Highlights of the clip: "Huckaburgers"; Colbert: "... outsourcing jobs?" Huckabee: "As long as they're not mine"; Colbert's foreign policy experience; Colbert's advice for Huckabee to "raise some serious scratch" and Huckabee's response to it; "Stay a Huckabee, not a Huckawas."

It was brilliant, and I think his visits to the Report really could help get Huckabee on the Republican ticket, as strange and unlikely as that seems. But then will he actually ask Stephen to be his running mate?
